Abstract

A foaming jig ( 35 ) with a refrigerator cabinet ( 13 ) is enclosed in a vacuum chamber ( 25 ); a metered quantity of a polyurethane mixture is then fed into the hollow walls of the refrigerator cabinet ( 13 ), making the foam to growth by generating a vacuum degree in the vacuum chamber ( 25 ) and into the foaming jig ( 35 ); the foaming of the cabinet walls ( 13 ) can be carried out in a comparatively short time, by using fast reactive polyurethane formulations.
